Abstract
There is provided a smoking material wrapper having micropores, wherein when the smoking material wrapper is divided into three regions at equal intervals from an upstream distal end based on the case where the smoking material wrapper is applied to a smoking article, an average porosity is greater as a region becomes closer to a downstream. According to an embodiment of the present disclosure, the micropores have a pore size of 10 μm to 50 μm, and are formed by a perforation method using plasma. The wrapper may maintain functionality as a wrapping material due to low visibility or the like, and may minimize a dilution ratio decreased due to burning of a smoking material unit while maintaining a basic dilution ratio when the smoking material wrapper is applied to a smoking article.
